Abstract

The invention provides a thermal power plant industrial cooling water system and a start and close control method thereof. The system comprises an industrial water pool, a first industrial cooling water pump, a second industrial cooling water pump, a third industrial cooling water pump, a first condensate pump cooler, a second condensate pump cooler, a third condensate pump cooler, a sealing oil vacuum pump cooler, an air compressor cooler, a first water feed pump booster pump cooler, a second water feed pump booster pump cooler, a first start furnace water feed pump cooler, a second start furnace water feed pump cooler, a furnace water circulation pump cooler, a water replenishing electric door, a water replenishing regulating valve, a recirculation regulating valve, a water supply main pipe electric door, a water supply main pipe exhausting electric door and a back water main pipe electric door. According to the thermal power plant industrial cooling water system and the start and close control method thereof, in the condition that the industrial cooling water system is fully closed, the industrial cooling water system is automatically started; in the condition that the industrial cooling water system operates, the industrial cooling water system is automatically closed; and human judgment is taken into account, and leapfrog operation of the programmed logic of the industrial cooling water system is achieved.

Description

technical field [0001] The invention relates to the industrial cooling water technology of a thermal power plant, in particular to an industrial cooling water system of a thermal power plant and a start-stop control method thereof. Background technique [0002] The main function of the industrial cooling water system of a thermal power plant is to provide continuous, high-quality cooling water for the important auxiliary equipment of the thermal power plant, take away the heat generated during the operation of the auxiliary equipment, and use it as a supplementary water for the circulating water tower pool to make up for part of the The amount of water removed by evaporation of circulating water. However, the industrial cooling water system of the existing thermal power plant cannot realize the automatic start of the industrial cooling water system under the state of full stop; it is also impossible to realize the automatic stop of the industrial cooling water system under t...
